Title: Flanged piles for reinforcing foundations - allowing formation of highly compressed solid ground zone
Inventor: ASAYAMA KINGO
IPC: E02D27/14
Filed: 1974-08-22
Abstract: The foundation assembly comprises several piles (1, 6) each having several flanges (3, 8) integral with the body of the pile. The flanges of each pile are spaced apart by fixed distances (C3, C8). The piles are arranged relative to each other so that the flanges on one of at least two adjacent piles are offset from those on the other pile when the piles are driven into the ground. The distance (L1) between the upper end (4, 9) of one pile body out of two adjacent piles andits uppermost flange is different to the corresponding distance of the adjacent pile, so that the flanges of the adjacent piles are vertically offset from each other.

Title: Doping profiles in SC crystals - are produced by diffusion of impurity centres consisting of nickel atoms using dissociative diffusion mechanism
Inventor: ISEGHEM PAUL VAN DR ING
IPC: H01L29/00
Filed: 1974-11-30
Abstract: The SC crystal is made of silicon, and before nickel diffusion it is either N-conducting, with an impurity centres concentration not exceeding 5 x 1015 atoms/cm3, or P-conducting; nickel is then diffused into the crystal at a concentration corresponding to the difference between the doping concentrations of different zones to be produced (N-N-; N-P; P-P+); at a temperature corresponding to the solubility of this nickel concentration in the SC crystal; then the crystal is cooled, so that zones with different conductance are produced.

Title: Machine tool retention device tension force control - has pressurised piston valve, and is spindle speed dependent
Inventor: BOEHRINGER HEINZ
IPC: B23B31/30
Filed: 1974-12-12
Abstract: Installation in a machine tool for control of the tension force of a retention device, which exerts a high tension force during rough machining and a lower force during fine machining. The tension force is variable by means of a pressure medium piston and a valve control. The side of the piston effective in lowering the tension force is connected to a pressure medium feed via a valve which has to open when changing from the one tension force to the other. The retention device is borne by a rotating spindle, and a device is provided for automatic selection of tension force which is dependent upon the speed of the spindle, so that with rising speed the tension force increase, and vice versa with dropping speed.

Title: Table tennis table with hinged supports - supports swing in two points on frame
Inventor: PAHL ERNST
IPC: A47B25/00
Filed: 1975-01-02
Abstract: This table-tennis table is fixed at each end to supports which each swing in two points on the frame. Each support consists of a vertical stand (e) which stands on a trapezium-shaped base (d) with three casters, so that when the table is folded upward the supports nest together and can be put away simply without dismantling. Lifting the two pieces of the table top in the middle cuases the two stands to travel towards, and into, each other. Consequently, the table carrying supports stay close to each other and the table top halves are pressed together edgewise.

Title: Stamp for cooling body ribs - has strip material fed into reciprocal vee form punch and die with sprung stripper
Inventor: KNIGGE REINHARD
IPC: B21C37/15
Filed: 1975-01-25
Abstract: The system is for production of cooling ribbed hollow cylindrical bodies e.g. for electric motor housings. The hollow body is produced from sheet strips (6) which are bent in three different folding directions during their primary bending stage such that roof shaped equal length leg type projections (8) are formed and the sections of the strips (6) which connect the projections (8) are bent to form a cylindrical body of enlarged interior dimensions which is welded together. In a second finishing stage both legs of all projections (8) are bent closer together to produce the cylindrical bodies of the requisite interior dimensions. A transport link (5) pulls the strip on after each forming stage.

Title: Switching circuit with capacitor charge operating transistor - has supply briefly connected to load irrespective of switch position
Inventor: GRIMM WERNER
IPC: H03K17/00
Filed: 1975-01-31
Abstract: The switching device uses a capacitor charge and discharge energy to operate a circuit that connects the load to the current supply irrespective of the switch state, from which the switch starts to operate. The switch-on time is determined by the capacitance of the capacitor and can, therefore, be defined precisely. This time is defined by a timing logic that can be chosen as required. The capacitor is charged via a Darlington pair and a resistor, when the switch opens. The capacitor turns on a pair of transistors that connect the supply to the load. A holding resistor ensures that the load remains connected to the supply until released by the timing logic.

Title: Heating pump for swimming pool heaters - uses separately positioned evaporator tube ends
Inventor: SCHNEEWOLF HANS
IPC: F25B13/00
Filed: 1975-03-07
Abstract: The heating pump has an air charged evaporator with parallel horizontal evaporation tubes, and a pressure reducing valve at the evaporator outlet, for a fluid cooling medium. The injection-and suction ends of the evaporation tubes are open separately into a distribution chamber positioned below the evaporator at its entrance, and a collection chamber located at the outlet. A throttle is positioned between each tube and the associated chamber. A compressor has a multi-way valve, to feed the compressed hot air to a condenser for normal heating, or to the evaporator for defrosting. The condenser is similar in construction to the evaporator and a collector is positioned between the two pressure reducing valves. The connection between collector and each valve is via parallel conduits each having non-return valves to block and free the passage.

Title: Regeneration of mixed bed ion exchange resins - with brine washing of anion resin followed by bed mixing and acid wash
Inventor: LADENDORF PETER DIPL CHEM DR
IPC: B01J49/09
Filed: 1975-04-26
Abstract: A mixed ion-exchange resin bed is first separated into its two components, the lighter anion resin on top; the latter is then given a brine wash.
